In fanfiction, Hiro and Zero Two often have a very deep and complex relationship. Their bond is initially based on their unique connection as partners in the Franxx. Hiro is one of the few who can tolerate Zero Two's more 'beastly' side. They grow to understand and rely on each other more as the story progresses. For example, Hiro's determination to stay with Zero Two even when others might be afraid of her shows the strength of their relationship.
In some fanfictions, there's a scene where Hiro stands up for Zero Two against the other pilots who are being judgmental. It's a powerful moment that showcases his loyalty to her. Also, the scene where Zero Two saves Hiro from a near - death situation and they share an intense, emotional embrace is quite memorable.
One possible plotline could be that Ichigo initially sees Zero Two as a rival for Hiro's attention. But as they go through various battles together, they start to understand each other's pain and loneliness. For example, they might be forced to work in tandem during a particularly difficult mission against a powerful klaxosaur. And gradually, they develop a mutual respect, which could lead to an unexpected friendship.
